SigmaPlot - HELP!!


I've posted a few times about graph/stats programmes here before. After a period of me trying to persuade my sup to purchase Graphpad Prism for the lab, she's told me that she thinks it's a bit too expensive - to be fair, I agree with her. I hate SPSS, and Excel is no good, so I'm left with SigmaPlot, which we have for free.

My question is - does anyone know of any good books or websites about using SigmaPlot, or have anything to share from their experiences of using it? The SigmaPlot pdf manual is 900 pages long, and rather scary for someone who's never used it before, especially for someone who doesn't want to use the majority of its features...

Thanks :)
